drm/amdgpu: fix IB test MCBP bug
1)for gfx IB test we shouldn't insert DE meta data 2)we should make sure IB test finished before we send event 3 to hypervisor otherwise the IDLE from event 3 will preempt IB test, which is not designed as a compatible structure for MCBP Signed-off-by: Monk Liu <Monk.Liu@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
